如何在jQuery中解析这个无效的JSON字符串？ [英] How do I parse this invalid JSON string in jQuery?

问题描述

我希望访问此数据属性中的各种数据位：

I am looking to access the various bits of data in this data attribute:

<div class="location" data="{id: 4, point: {lng: -71.413364, lat: 41.673681}, category: 'Restaurant'}">

当然，数据属性很容易在jQuery中实现。但字符串似乎是一种非标准或无效的JSON形式。我已经尝试过JSON.parse（）以及分割数组的基本JS方法。从各方面来看，它似乎只是一个无效序列化的字符串。

The data attribute is easy enough to reach in jQuery, of course. But the string seems to be a non-standard or invalid form of JSON. I've tried JSON.parse() and also a basic JS method of splitting the array. By all accounts, it just seems to be an invalidly-serialized string.

我是否需要重新格式化数据字符串？ （它不是来自我，它被其他惯例使用，我宁愿不打破，所以......）

Will I need to reformat the data string? (it doesn't come from me, and it's used by other routines that I'd rather not break, so...)

推荐答案

通常我会说这很危险（实际上我现在会说），但请尝试：

Normally I'd say this is dangerous (and in fact I'll say it now), but try:

var decoded;  eval("decoded = " + $('div.location').attr('data'));

这是无效的JSON，因为没有引用标签。

It's invalid JSON because the labels aren't quoted.
